Abstract: Polyethylene bottles of 20 and 250 ml capacity and Eppendorf reaction vessels had been tested for constant weight, different sizes of bottles in cylindrical and cubicform, and Eppendorf reaction vessels for water permeability. The cylindrical vials of laboratory quality and the Eppendorf vessels showed acceptable results in both the constant weight and water permeability test, whilst the cubic vessels showed remarkable losses in the water permeability test if equipped with standard caps. Replacement of this caps by those from normal laboratory vials (KAUTEX) minimizes the water lasses to normal values.
